Collared Sparrowhawk and Brown Goshawk comparison

This morning I was alerted to some action happening outside my accommodation. The Pied Butcherbirds and Magpies were making a fuss so I grabbed the camera and went outside.

A couple of Collared Sparrowhawks were giving a young magpie some trouble and the older magpies were swooping the sparrowhawks. One of the Collared Sparrowhawk obligingly came and sat on the power line near me and I took a couple of photos.

After the photos I wondered how I knew it was a Collared Sparrowhawk and not a Brown Goshawk. For a start it seemed small, especialy around the head region, the legs seemed long, and I couldn't see the "brow" over the eye that make the goshawks seem angry. The final part was the more rounded tail. I looked back through my photos of a young goshawk from earlier this year (see that post here) and thought it might be useful to put the two birds side by side in a photo to help explain.So the key points are: the size of head, around the eye, the length of feathers on the legs, and the tail. Hope this helps someone in the future identify which one is which.

  1. Nice pictures, Richard. It is a good comparison, but still if one flicks past my ears in the bush, I can often be left wondering...? Female sparra, or male gos?

      Thanks I would imagine if one flicks past your ear, it would be a Whistling, Birder that is as I think I would give out a "Whewwww". :-) unless I get a good look at the tail while perched, or the eye area in sunlight, I struggle with telling the difference normally. This morning was unusual in that sense.

  2. This is fantastic! I have been seeing a bid of prey either one of these for years not far from our house - have never managed a decent photo and am unsure on which type of bird it is. It always poses for me on a fence-post when I am without my camera! I like the description of the "eyebrow making it seem angry". I will have a better look at this. Thankyou.
